To all whom it may concern:

Be it known that I, ALBERT DAHLIN, a citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented new and useful Improvements in Snow-Flows, of which the same to one side or the other of the track or beyond both sides thereof as may be desired or as conditions may require.

Another object of the invention is to so arrange the parts of the plow that the snow is gradually lifted from its position on the track and then cast laterally bevond the sides of the track along lines'of least resistance thereby making it possible to readily remove the snow from the track in the event that it is packed solid or is of extreme depth.

With these objects in view the plow includes a wheel mounted frame or platform having cutters positioned at the forward 1 end thereof and adapted to make the initial incision, in the snow. An upwardly and rearwardly inclined surface is' mounted upon the said platform 'and a wedge-shaped prow is mounted at the rear end of the said surface. The said prow is provided at its forward end or apex with hinged doors or panels and partition walls are movably mounted from positions within the prow to positions in advance of the same and'the said walls may be extended in order to cast thesnow to one side or the other of the snow plow. The snow plow is provided at its opposite sidesand in advance of the said prow with wine gatherers and casters adapted to remove the snow which lies beyond the opposite sides of the track and cast the same still farther beyond the sides of the track in order that ample room is provided for the major body of snow which is lifted from directly over the track and cast beyond the sides of the same.

In the accompanying drawings :Figure 1 is a side elevation of the snow plow; Fig. 2 is av top plan view-of the same: Fig. 3 is a front elevation of the same; Fig. 4 is a rear elevation of the same; Fig. 5 is a h0ri-,.

ports the forward end portion of the said frame and is located under the forward portion of the inclined surface 4 as'best shown in Fig. 1 of the drawing.

A wedged-shaped prow 6 is mounted upon" the platform at the upper rear end of the surface 4 and the forward corner or apex of the said prow consists of two hinged doors" or panels 7. Side walls 8 are mounted upon the forward portion of the'surface 4 and the said walls at their rear ends terminate short of the prow6 as best shown in. Fig; 1 of the drawing. Wing scoops 9 are mounted at the upper rear portion of the side walls 8 and are adapted to encounter the upper layers of snow beyond the sides of the track rail and cast the same still farther beyond the sides of the track rail and thereby providing room for the reception of the'major portion of the snow which is mo ed from directly over the track rails. Partitions 10 are normally retainedwithin the opposite sides of the prow 6 and the said partitions are mounted upon supporting wheels 11 and adapted to move along the upper side of the inclined surface 4. Cables 12 are attached at one end to the partitions 10 and the said cables are trained aroundpulleys 13 and then wound upon drums 14.

When the snow plow is in operation and it is desired to cast the snow beyond both sides of the track the partitions 10 are housed within the prow 6. Consequently it will be seen that as the snow passes up the 'surface 4 it will be divided by the point of apex of the prow and split so that part is cast to one side and part to the opposite side of the track. Cutting blades 15 are mounted at the lower forward edgeof the surface and the said blades make the initial incision in the snow. When it is desired to cast the snow to one side of the track only, one of the panels '2 is swung to an open position, that is to say it is-swung forwardly and a section 16 at the lower end thereof is face 4. When one of the drums 14: is turned whereby the cable attached thereto is unwound therefrom and the partitions 10 which is connected with the said cable moves down along the surface 4 in advance of the prow 6 and toward one of the side walls 8. Corn sequently the partition closes the edges at one side of the snow plow while the edges at the opposite side are left open. As the snow comes back from the forward end of the prow it strikes the said partition and is deflected over through the edges and out beyond the side of the track. Brushes 17 are journaled for rotation in advance of the track 1 and are adapted to operate upon the track rails to remove the snow therefrom. The said brushes are rotated by means of chains 18 which in turn are operated from the axles and wheels of the truck 1. Scraper plates 19 are mounted upon the platform and in advance of the brushes 1? and the snow which is cast up by the said brushes strikes the said plates 19 and is deflected to one side or the other of the track rails. Teeth 20 are mounted at the forward edge of the surface 4 and serve to sever the snow as the plow moves in a forward direction. Spring pressed fenders 21 are mounted at the rear portion of the sides of the frame 3 and serve to compress and spread the side Walls of the ditch or furrow which is cut in the snow by the plow.

From the foregoing taken in conjunction with the accompanying drawings, it will be seen that a snow plow of simple and durable floater of this patent may be obtained for five cents each, by addressing the structure is provided and that the snow plow may be eliiciently operated to promptly remove the snow from the road bed and cast l. A snow plow comprising a wheel mounted frame having an upwardly and rearwardly inclined surface, side walls mounted at the lower forward portion of the inclined surface, a prow mounted at the upper rear portion of the inclined surface, hinge-panels forming the apex of the prow and partition walls normally housed within the sides of the prow and adapted to be projected beyond the prow toward the first mentioned side walls.

2. A snow plow comprising a wheel mounted frame having an upwardly and rearwardly inclined surface, side walls located at the lower forward portion of the said surface, a wedged shaped prow mounted at the upper rear portion of the platform. hinged panels forming the apex of the said prow, partitions normally housed between the side walls of the prow, wheels support-- ing the said partitions, and winding mcchanisms for controlling the movementof the partitions, the said partitions adapted to be extended toward the first mentioned side walls.

In testimony whereof I affix my signature.
